Hi all my name is Carl im a 32 yr old guy who lives with my partner of 6 years Lauren. It was the end of last November and Lauren had a Saturday night out planned with her best mate Sophie. Sophie is an attractive blonde I would say a size 10/12 shoulder length blonde hair with average size tits and a nice curvy arse. Sophie is a good laugh we all get on well she comes across as a nice girl but has a wild side my mrs had told me many of stories about the things sophie has got up to with men especially once she has had a drink. On t e Saturday night in question I had no plans and Lauren and Sophie went out as planned. It was about 1.30 when they returned both pretty tipsy but Lauren was obviously the more drunk of the two. Lauren didn't stay up long once they returned and soon went up to bed leaving me and Sophie making small talk for 20 mins or so before I said I best let you get some sleep as Sophie was staying over and sleeping on the sofa. I headed off to the bedroom and began to undress, just I I strpped to my boxers Lauren turned over in bed complaining that she was hot and asked if I had left the heating on which I had. Without thinking I headed downstairs in just my boxers to the hall way and was stood there turning the heating down when Sophie appeared in the living room doorway wearing only a bra and thong to see what I was doing. Sorry I said I left heating on and Lauren is saying shes hot. Ahhh ok Sophie replied is she ok she asked. This led us to standing there chatting a little more both of us in just our underwear which didn't seem to bother her infact I think we both looked each other up and down a few times before Sophie asked if it was ok to get a glass of water, yeah that's fine I said I might as well get myself one. With that I followed Sophie into the kitchen watching the movement of her arse as she walked. We got to the kitchen and Sophie poured each of us a glass and as she tuned she smiled and said omg carl glancing towards my crotch. I looked down and realised my semi hard cock was bulging in my tight boxers the outline clearly visible. I cant believe your getting hard you pervert she said jokingly as she past me my glass. I took my glass off her she stepped back still looking at my bulge. I could feel myself blushing and apologised but she just found it funny and said that will teach you for perving but then turned around leant forward slighty slapped her bum asking if that's what I was looking at. I didn't know what to she after all this is my gf best friend. But my cock was clearly still growing. she then walked towards me reaching out and slipping her fingers in the band of my boxers asking me to show it her. Don't be silly Sophie I said holding her wrists so she didn't pull them down Lauren is upstairs. She said just let me have a look im not exactly gonna tell anyone am I. My resistance on her wrists weakened and she slipped my boxers down exposing my semi hard cock oh wow she said Laurens a lucky girl isn't she as she watched it cock to its full 7". I like the big head she commented. I was so nervous in case Lauren came down the stairs or heard us but I thought it was to late now. Have you had a good look now I asked mmm oh yes she said I reached down to pull my boxers up but she stopped me half way up and said let me give it a kiss goodnight, with that she leant forward and playfully kissed the tip of my cock she looked up at me I kinda just froze I never said a word and she slipped to her knees looking up at me the whole time and began to suck my balls before slowy running her tounge up my shaft and taking my head in her mouth. Sophie stop I said this Is wrong sssshhhhh I wont tell she said before continuing to suck me. It felt so good I had no resistance in me and I stood there as she upped the pace giving me one of the horniest blowjobs ive ever had. more to follow .......
